Definitions

  • the invention relates to a drive-over bridge for ramps with a pivotable bridge plate, the front section of which can be pivoted about a horizontal axis relative to the rear part, the rear part of the bridge plate standing approximately vertically upwards in the rest position of the bridge and the section of the bridge plate being arranged approximately horizontally is and in addition, in the operative position of the bridge, the section and the rear part are aligned and the bridge plate as a whole is arranged essentially horizontally.
  • the front section is pivoted freely and underpinned in the rest position of the bridge by a stop on the rear part of the bridge plate.
  • the front section at the free end is expediently designed to be slidable and unrollable.
  • the invention is based on the consideration that the rear part of the bridge plate is pivoted from the vertical rest position into the approximately horizontal operative position by hydraulic cylinders or similar pivoting means, but by means of these means is predominantly pivoted from the approximately horizontal active position into the approximately vertical idle position. If the section is now undertaken in the rest position of the bridge, it retains its horizontal position solely on account of its own weight. If the rear part is now swiveled downwards to put the bridge into operation, the section follows this movement, but after a certain swivel path it hits the surface of the ramp and then automatically folds further with the lowering movement of the rear part until it finally joins in the rear part is aligned. When the bridge plate is swung up, the front section maintains its horizontal position, which it cannot leave in the vertical end position of the rear part, because it is then underpinned.
  • a drive 3 for the movement of the drive-over bridge on a rail.
  • the lower or rear part of the bridge plate 5 is located within this frame when the bridge is in the rest position.
  • the lower or rear part 4 is pivotable about a horizontal axis 6, with the aid of a working cylinder 7.
  • a front section 8 is articulated, namely the articulation about a horizontal axis, which is designated by 9 .
  • section 8 In the rest position of the bridge plate 5, the section 8 assumes a horizontal position in order to be able to accommodate a long bridge plate 5 in a comparatively low building or the like. In this position of section 8, it bears against an abutment 10 which extends transversely to part 4 and is angled downward at the free end. This bend is designated 11.
  • the strut 2 is provided at the top with rollers 12 which are guided in rails, not shown.
  • section 8 lies freely on the abutment 10 when the part 4 is in the rest position, that is to say in the vertical position.
  • section 8 retains its position due to its own weight until the rollers 14 located at the front of section 8 surface 16 of the ramp 17 touch. This begins the unfolding movement of section 8. This unfolding is finished when the bend 11 hits surface 16 and finds its abutment here.
  • the bridge can be used to bridge railway tracks in front of ramp 17, e.g. Railway wagons are to be loaded or unloaded from the front.
  • the section 8 is thus pivoted freely on the part 4; however, it is prevented by the abutment 10 from adopting a position in which it assumes an angular position with respect to part 4 which is less than 90 °.
  • the joint with the axis 9 thus allows a free pivoting of the section 8.
  • this joint can be designed in such a way that it prevents movement in the direction of arrow 18 in the operative position of the bridge plate 5 if the section 8 should be pivoted upward beyond the plane determined by the part 4 or the attempt should be made to effect such a pivoting.
  • this joint can be equipped without the stops required for this limitation. It is then possible to swivel the section 8 backwards from the abutment 10 by approximately 270 ° in order to e.g. To hang up on part 4, there should be a wish.
  • section 8 always pivots automatically and also remains at rest, due to the weight of section 8. It is also important that the articulation point of part 4 or the height position of axis 6 must be selected in this way , namely with a sufficient length of the part 4 that when the section 8 strikes the surface 16, the section 8 forms an angle with this surface which is less than 90 °. This ensures that the section 10 can unfold during a further lowering movement of the part 4, the rollers 14 also being important.
